1614年榆社地震与1615年平遥地震

THE YUSHE EARTHQUAKE IN 1614 AND THE PINGYAOEARTHQUAKE IN 1615

本文通过对有关资料的分析、考证，论述了现行地震目录中１６１４年平遥、榆社一带的６级地震应是两次地震。１６１４年榆社地震震中在榆社河南街村一带。当时，河南街村人口不足２００，处于易遭地震破坏的孤立突出的地貌部位，地震时遭中等程度破坏，房屋遭破坏的比例５０％以上。烈度为Ⅶ度、震级为５级。地震发生前后的４０天中，在该地震。１６１５年平遥地震发生于山西断陷带的太原盆地东侧，震中烈度Ⅶ度，震级５级。文中还给出了这二次地震的震中坐标，并论证了不是一次地震而是两次地震缘由。

Based on analysing and examining ralated data, the authors believe the 1614 earthquake of M6 occurred around Pingyao and Yushe and listed in present earthquake catalogue to be two events.The epicentre of the 1614 Yushe earthquake lain around Henanjie village which had a population of less than 200 at that time and was situated in isolated and projecting geomorphological position tending to be damaged by earthquake. Henanjie village was damaged in medium degree by the earthquake, with magnitude of M 5 , intensity of VII degree,which occurred in depresson basin of late Cenoic Era in swelling region east of Shanxi faulted- subside zone,and over 50% of houses in the vlliage were destroyed.During period of 40 days before and after the earthquake, five events with M 3 ～5 occurred within about 30 Km in the basin, and the Yushe earthquake was probably the maxium event in the swarm.The 1615 Pingyao earthquake occurred in east flank of Taiyuan basin in Shanxi faulted-subside zone, having epicentral intensity of VII degree and magnitude of of M 5 .In this paper, the epicentral coordinates for the two events are given, and also the reason that they were two events but one is discussed.
